I think this is fixed by this series of commits:

  285f63e80 * store: Support 'ssh://' URIs in 'GUIX_DAEMON_SOCKET'.
  e53783372 * ssh: Decompose 'connect-to-remote-daemon'.
  615c5298f * ssh: Move 'open-ssh-session' to (guix ssh).
  ba97e454b * offload: Avoid using '_' as a 'match' pattern.
  3dff90ce3 * store: Add support for remote connections via 'guix://' URIs.
  3b5cd17a9 * store: Add 'system-error-to-connection-error' macro.
  1397b422e * store: 'GUIX_DAEMON_SOCKET' can now be a URI.

with the caveats given here:
